Installed Winamp Basic Full 5.33 on Windows Vista. After reboot to complete installation, got the Windows Boot Manager screen with error "Windows failed to start. A recent hardware or software change might be the cause." The problem file is PxHelp20.sys. Status code 0xc0000098. Info: "Windows failed to load because a critical system driver is missing, or corrupt."

I have tried to repair using the Windows disk, which will not work. I cannot boot into safe mode, I cannot run a system restore, and I cannot even see a Windows directory using command prompt to browse for this file. The only option left is a complete Windows reinstall (no thanks).

Update: when I go into command prompt, apparently my C & D drives have swapped so windows is on my D drive. I haven't done anything today other than install Winamp. Is there anything in the Winamp install that would cause this behavior? I've never seen anything like it and I don't know how to change it back.

PxHelp20.sys is the main Sonic Burning Engine driver.
I doubt if Sonic is compatible with Windows Vista, and "Sonic Ripping/Burning Support" should probably be unchecked by default in the Installer Options, or not included at all, at least until Sonic provide us with a Vista-compatible version.

Thanks for the replies. My partitions got swapped after the Winamp install, so swapping cables won't help. I ended up buying a new hard drive and installing Vista fresh. What a nightmare. I was trying to install Winamp because I read about the Winamp plugin to manage ipods--(Anapod just trashed my ipod, so I'm looking for an alternative). I guess I will have to live without my ipod until someone can make a Vista-compatible ipod manager. I'll keep my eye on Winamp but I'm really afraid to try to install it again right now.
